IMPROVEMENT IN DOORTBELLS.

Specification forming part of Letters Patent No. 152,925, dated July 14, 1874; application tiled March 26, 1874.

To all whom it may concern:

Beit known that I, WILLIAM E. SPARKS, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in DoorBells 5 and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, inV

Figures l and 2, sectional views of the invention.

rI`his invention relates to an improvement in that class ot' gong-bells designed to be applied directly to the door or to the wall beside' the door 5 and the invention consists in a spindle extending` through the'door or wall, as the case may be, provided with a pull upon the outside and a spring to return the spindle, in

connection with the hammer, the axis of which is at right angles to the axis ot the bell and spindle, so that the movement ot the spindle imparts a corresponding rota-tive movement in a plane parallel to the axis of the bell to strike the bell-hammer, the operative mechanism all arranged within the circumference ofthe bell, as more fully hereinafter described.

A is the base, which should correspond to the outline of the bell, and is secured to the wall or door B, or wherever it may be desired to fix the bell. IC is the spindle, which extends through the wall or door B, provided with a knob, D, or other pull, upon the oppo site side, and must enter within the circumference of the bell E, which is secured to an arm, F, extending from the base. A suitable spring, G, tends to draw and hold the spindle in its extreme inward position. H is the hammer, hung upon a pivot within the circumference ofthe bell, at right angles to the axis ot the bell, and connected with the spindle C, so that by pulling the spindle a corresponding rotative movement in a plane parallel to the axis of the bell will be imparted to the hammer, causing it to strike the bell. In Fig. l this connection is made by the pinion I, so that the axis of the pinion will be the center of motion of the hammer, and the rotative movement of the hammer will be in a plane parallel with the axis of the bell. Instead of the toothed connection between the spindle and wheel I, it maybe as in Fig. 2, an arm, I', in connection with the spindle C.

I claim as my invention- In combination with the base A and bell E, the hammer H and spindle C, arranged within the circumference ot said bell, the spindle and hammer having their axis at right angles to each other, and connected substantially as described, ivhereby the movement of the spindle parallel to the axis of the bell imparts a corresponding' rotative movement to the hammer in a plane parallel to the axis ot' the bell, substantially as set forth.

WILLIAM E. SPARKS.
